Mexico Boosts Sterile Fly Dispersal as US Reopens Cattle Trade
USDA says 700 cattle a day will cross Douglas in the first week as inspections and RFID ear tags are required to limit New World screwworm spread.
- On Monday, August 24, the United States Department of Agriculture reopened the Douglas, Arizona, port of entry to cattle from Sonora, Mexico, initiating a phased resumption of trade disrupted by New World Screwworm concerns since late 2024.
- Driven by acute cattle shortages and high beef prices, the United States resumed imports after NWS infestations had intermittently shuttered the border since November 2024, straining domestic processing capacity.
- USDA veterinary inspections and new radio-frequency identification ear tags are mandatory for all imported cattle. The Animal and Plant Health Inspection Service identifies Sonora as low-risk due to its "strong, well-established inspection programs."
- Officials will permit around 700 head daily during the first week, rising to 1,300 head later. While the National Cattlemen's Beef Association supports the move, rancher group R-CALF argues Mexico must fully eradicate NWS before trade resumes.
- Future openings at Santa Teresa and Columbus, New Mexico, depend on assessing the Douglas reopening's success. The government continues investing in sterile insect technology, currently dispersing 100 million sterile flies weekly to suppress NWS populations across the region.
